7 '0 all whom it may concern:

. Be it known that I, JOHN P. Wars, a citizen of the United States,residing in Nyack, county of Rock] and, and State of N ew- York, haveinvented a new and useful Improvement in Seams for Sewed Articles, ofwhich the following is a description.

This invention relates to seams for sewed articles, and has specialreference to seams which are made over the edge, or edges, of pieces offabric.

Amon the objects of this invention may be note the following: to producea seam. for sewed articles containing a plurality of threads forming anornamental edging, selvage or finish for the work; to produce an edgingfor work composed of two needle or upper threads, and a single lower orlockin -thread; and to provide a seam which wi 1 be not only ornamental,but which will form a wearing edge for the ,work- With the above objectsin view, my invention consists in the features andcom- In the drawings:Figure 1 isa perspective View showing the top surface of the work, thelatter consisting of two pieces of fabric superposed and having theiredges overstitched in accordance with my invenl tion; and Fig. 2 is aperspective view of the work of Fig. 1, but showing the bottom surfaceofthe work.

Primarily, it should be understood that, although this scam isillustrated in connection with two pieces of superposed fabric, it maybe applied to a single piece of fabric for the pur ose of giving to thelatter a selvage or nished as well as ornamental edge, thus giving thesame greater durability and increasing the wear of its edge, es-

eciall if the fabric be loosely woven or Referring to the drawings, 1indicates the fabric, 2 indicates one of the top threads and 3 indicatesthe other of the top threads, while 4 indicates the locking-thread. Thearrow 5 indicates the line of feed. The thread 2 is manipulated so as toform a singlle line of straight stitching on the top surface-of thework, the said thread being assed through the work from the top suraceand formed into loops 2 at the bottom surface thereof. The thread 3 isalso passed through the work from the top surface forming the loops 3 atthe bottom surface of the 'work; but on the top surface of the work saidthread 3 is carried over into the path of the loops of the thread 2, soas to surround the loops 2 at the point where the latter ass into thework at the top surface thereoi:

being indicated y 3", said loops being thus held by the straight line ofstitching of the thread 2 on the topsurface of the work, as clearlyshown in Fig. 1. A loop 4" of the locking-thread 4, is assed throughboth the loo s 2 and 3 of t e' respective threads 2 ant 3, extends fromthe bottom surface over theedge of the work and surrounds the loops 3*at the point where they pass into the work at the top surface thereof,said locking-loops 4 thus holding the said loops 2" and 3 closely unitedin pairs on the bottom surface of the work and being in turn held by theloops 3 on the top surface of the work, the said loop 4 extendin thusfrom the bottom surface of the wort across the edge and a distance overthe top surface thereof. By thus manipulating the locking-thread, a,straight line of stitching of said thread occurs on the bottom surfaceof the work and loops of said thread are laid in parallelism over theedge of the work.

From the above description it will be seen that on the bottom surface ofthe work a straight line of stitching occurs which holds loops of therespective top threads in parallelism and a loop of one of said topthreads grouped or paired with a loop of the other top thread, while onthe top surface of the Work a line of straight stitchin occurs whichholds loops of a top three which latter is iven a zigzag form and inturn holds the %oops of the lower thread. Obviously, the tension )lacedupon either the top threads or the l ockingthread-will, in a measure,change the location of the several loops; that is to say, the loops ofthe to threads which are on the bottom surface. 0 the Work may be drawn,by tension on the locking-thread; into such position as to be locatedmidway between the two surfaces of the work. instead of at the bottom ede of the work, as shown in the figures, or t e bights of said loops maybe located at any point between the point of enetration of thread 3 onthe top surface 0 the work and the point where said loops emerge fromthe fabric on the bottom surface thereof, or the tension on the threads2 and. 3 may draw tration of the loops 3", or to a position be- A tweenthe points of penetration of the loops of the threads 2 and 3, thusgiving to the locking-thread on the bottom surface a zigza form. a a

i mong the advantages of this seam may be noted the followin Anartificial selvage is roduced on the e ge of the work which wi 1 savethe latter from wear and will give to the edge of the work a finishedand or nate a peara'ncei-the edges of knit goods and 0t ierelasticfabrics can be prevented from inordinately stretching, pullingout or raveling; and an ornamental finish for the edges of work isproduced.

Having described my invention, what I claim and desire to secure byLetters Patent is:

1. A seam for sewed articles com risin the fabric and a plurality ofthrea 5 said seam being-characterized by having a thread forming astraight line of stitching on the top surface of t ie fabric, loops of asecond thread 1 'ing on the top surface of the fabric and enchained withthe thread of said line of stitching, and loo )3 of a third threadextending over the edge of the fabric and enchained with the loops ofthe second thread on the top surface of the fabric, and with loops ofsaid first two mentioned threads below the top surface of the fabric.

2. A seam for sewed articles com rising the fabric and a pluralit Y ofthree s, said seam being characterize by having two threads enchained onthe to 1 surface of the work, one forming a line of straight stitchingand the other laid in loops at an angle to said stitching, and having onthe bottom surface of the work two independent sets of loops, the loopsof one set being inclosed respectively by the strands of the loops ofthe other set, and both said sets of loops being joined to the topsurface 100 s by other loops extendin across the edge 0 the fabric;

3. A seam or sewed articles com risin the fabric and a pluralit ofthread sai seam being characterized y having two independent sets ofloops on thebottom surface of the fabric and a straight line ofstitching on the top surface of the fabric, the loops of the respectivesets on the bottom surface of the fabric being arranged in pairs and oneof each air mclosin the other, and said sets of oops being oined withthe straight line of stitching on t e top surface of the fabric by twoenchained 100 s which cover the edge and top surface of t e fabric.

4. A seam for sewed articles com risin" the fabric and a plurality ofthree 5, said seam bein characterized b having the loops of two inependent threa 5 passed throu h the :work from one surface to the other,said 100 5 being joined in pairs and brought toget er at the same ointon the fabric by the. loop of a third thread assed therethrough and overthe edge of tlie fabric, and a line of zigzag stitchin joining the saidloops of the third thread and the loops of one of the said independentthreads.

in testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
